Sankey diagrams are a unique data visualization technique that have become increasingly popular in recent years, particularly for visualizing complex flows of quantities between different nodes or categories. In this article, we’ll explore the power of Sankey charts, their creation, and various applications in different fields.
Understanding the Basics of Sankey Diagrams
Sankey diagrams are graphical representations of flows between nodes, with the width of the lines representing the volume of flow and the colors indicating different categories. They were first introduced by Scottish engineer Matthew Henry Phineas Riall, who used them to represent energy flows in industrial plants. Since then, Sankey diagrams have become a popular tool for visualizing complex networks and flows in various industries, including engineering, finance, and biology.
Creation of Sankey Charts
Creating a Sankey chart requires a few simple steps, but to make it easier for non-technical users, various software tools are available that can generate custom Sankey diagrams based on user inputs. Some popular tools for creating Sankey charts include Microsoft Power BI, Tableau, and Sankeyviz by Datawrapper.
To create a Sankey chart, users need to provide inputs in the form of data tables or CSV files that contain information about the flows, nodes, and associated values. The software then generates a chart that can be customized in terms of colors, line styles, and node arrangements. Once created, the chart can be exported as an image or HTML code that can be embedded on websites or shared via social media.
Applications of Sankey Diagrams
Sankey diagrams are useful in various fields that require representing flows of quantities between different nodes or categories, including:
- Engineering – Sankey diagrams are used to represent energy flows in industrial plants, pipelines, and other engineering systems.
- Finance – In finance, Sankey diagrams can be used to represent flows of money between different financial institutions, accounts, and transactions.
- Biology – Sankey diagrams can represent the flow of nutrients, energy, and other substances between different ecosystems or organisms.
- Business – In business, Sankey diagrams can be used to represent flows of resources, profits, and other quantities between departments or business units.
Visualization of Complex Flows
One of the key advantages of Sankey diagrams is their ability to represent complex flows in a simple and intuitive way. Flows between different nodes are represented by lines that can be color-coded, sized, and labeled for easy interpretation. This makes it easy to compare flows between different categories and to identify patterns, trends, and outliers in the data.
Customization of Sankey Diagrams
Sankey diagrams are highly customizable, making it easy to tailor them to specific needs and audiences. Users can adjust various parameters such as color schemes, font styles, and node arrangements to create visually appealing and easy-to-understand charts. This customization also makes it easier to incorporate multiple data sources and to represent different types of flows in a single chart.
Conclusion
In conclusion, Sankey diagrams are a powerful tool for visualizing complex flows of quantities between different nodes or categories. With the help of various software tools and customizable features, it is easy to create compelling Sankey charts that can be used to represent data in various fields, including engineering, finance, biology, and business. By leveraging the power of Sankey charts, users can gain a deeper understanding of complex data and make more informed decisions based on the insights derived from these charts.
